Modify

<application
android:name=".MainApplication"

to

<application
android:name="com.company.mobile.MainApplication"

If you've modified the package name then replace it with the one.

Also make sure that in manifest you're importing the correct package

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:dist="http://schemas.android.com/apk/distribution"
      xmlns:tools="http://schemas.android.com/tools"
      package="com.company.mobile">
